The Hoyer Heights neighborhood is located within the 1NE Watershed and experiences flooding during large storm events. This project is part of the larger 1NE Stormwater Management Initiative led by the Mississippi Watershed Management Organization (MWMO) in partnership with the City of Minneapolis (City) and Minneapolis Park and Recreation Board (MPRB), and was initially developed during the 1NE Watershed Planning and Preliminary Design project. The City retained SRF to complete a feasibility study on implementing storm sewer improvements and tree trenches in conjunction with the planned street reconstruction project for the neighborhood. This led to the final design of the full street reconstruction project, including storm sewer improvements, implementation of tree trenches on three streets as a pilot project for the City.
The roadway design replaced excess pavement with selected parking bays, provided additional boulevard width, curb extensions, and ADA complaint crossings to improve the pedestrian experience in the neighborhood. SRF coordinated the design details closely with the City’s green infrastructure coordinator, project engineer and maintenance staff to develop a design that maximizes the capture of urban runoff, provides robust pretreatment, and is maintainable. SRF’s landscape architects developed planting plans for the tree trenches that will enhance the streetscape and will provide habitat patches in the urban watershed. SRF is also assisting the City with obtaining grant funding from the MWMO to install the tree trenches as a water quality improvement.
